    5 of 5 stars  Great product
    By Janet in Odessa, MO on 04/15/2014
    Verified Purchase

    This product performed exactly as advertised. We only treated half of our pond at a time, according to recommendations, so we will be purchasing another bag very soon. We couldn't be more satisfied as we have tried EVERYTHING to get rid of the horsehair algae problem. This looks as if it will work and does not harm fish nor fowl!

    5 of 5 stars  GreenClean Pro better than Cutrine Plus
    By in Jackson Hole, Wyoming on 06/25/2013

    I treated half of one side of my half-acre fish pond with GreenClean Pro and the rest of that side with Cutrine Plus, which is what I had been using for two years. Within two days the results were dramatic; the algae on the rocks was almost gone with GreenClean, but it took another three days for the Cutrine to eliminate the algae. I'm sold! Great stuff.

    4 of 5 stars  Great Product
    By H in Genoa, OH on 06/26/2016

    This product works great around edges of pond where algae seems to appear most frequently. The consistency is like table salt. It is easy to distribute and sinks nicely where you throw it, unlike some products I've used that float away and sink where ever. The water temp and sun are important. I didn't give it 5 stars because I'm not sure if it works that well on deep pond floor algae. Could be I'm not using enough. Also wish it worked in cooler temperatures when algae first appears.

    5 of 5 stars  Works great!
    By Steve in Morris Plains on 04/23/2016

    This is just the thing for killing string algae in my pond. And so much more economical that the little tubs they sell at the pond store. Just be careful with it - it is twice the strength of the over-the-counter stuff, so you should use about half as much of this concentrated chemical

    4 of 5 stars  good for small ponds
    By Greg in Livermore CA on 04/06/2015
    Verified Purchase

    This product works well in small ponds, but is too expensive for a large pond. I have a 24,000 gallon pond. 50 lbs will not keep it clear for a year. People with acre size ponds will go broke trying to get rid of algae with this product. Copper kills algae in large ponds, but kills fish. Likewise chorine can make a small pond sparkle, but kills fish. I have used this product for 3 years and it seems to not have harmed my fish. Other reviewers seem to either love or hate this product. The ones with small ponds like it, the ones with large ponds hate it.

    I received great advice from you, and I used 100 pounds of the Green Clean and two weeks later, I put 3 bacteria balls in our lake. The horsehair algae appears to be clearing. This will be the first time in 3 years that algae is under control in our lake. Thank you so much!

    5 of 5 stars  Works great!!
    By Sun in Jackson Hole, Wyoming on 07/10/2014
    Verified Purchase

    I've been using this now for two years. I have a pond, with trout in it, that is about a half acre and is 20 feet deep at the deepest place. The only time the weeds get ahead of me is when I don't use enough. The moss was getting bad because I was out of GreenClean Pro Algaecide. I got my shipment of two bags yesterday. This morning I skimmed as much moss off the top as I could. Then I applied GreenClean Pro liberally, using both bags to do about half of the pond. Immediately the moss started detaching from the rocks and floating to the surface, then drifting toward the outlet. I have continuous water running through it, from my well. The shore looks very clean right now, with moss on just a few places where I missed. I kept back part of a bag to do those spots. It doesn't harm the fish, either. GREAT STUFF!

    By in Geneva, IL on 08/12/2013
    Verified Purchase

    The GreenClean Pro Algaecide is a product that really works, and still preserves the balance of your pond. All my beneficial bacterial survived and thrived as the algae was destroyed. I have many KOI and it never bothered them in the slightest way. I appreciate having a product that is this easy to use, and is so effective. You have me as a customer for life!

QI have an 8000 gallon man made pond. How much GreenClean per 1000 gallons? How often can I put it in?
The pond is in the AZ sun much of the day and algae can grow fast. How much should I use as a preventative?

AThe label states for high algae growth you should use between 2 and 10 Tablespoons per 1000 gallons of water.  On the first treatment you would probably want to use the 10 tablespoons per 1000 gallons of water if growth is high.  The label just says to re-treat as needed, just do not re-treat within 48 hours of the last treatment.  Environmental conditions determine how fast the algae re-grows and how often you will need to treat.  The label does state that after you treat initially with the up to 10 tablespoons that for maintenance you should use between 1 and 3 tablespoons per 1000 gallons of water.

QDoes GreenClean Pro Algaecide require running water to activate it?
We have an ornamental pond with a waterfall and have turned off the pump unit before using the green clean. Should we leave the water running or will it work with the pump off and a dry run to the pond portion?

A

The water pump needs to be running when using GreenClean Pro Algaecide. This will allow the product to work properly on the algae inside of the pond. The mixing ratio is 1-3 teaspoons per 1000 gallons of water.
